[flang][driver] Add `-fdebug-dump-parsing-log`

This patch adds `-fdebug-dump-parsing-log` in the new driver. This option is
semantically identical to `-fdebug-instrumented-parse` in `f18` (the
former is added as an alias in `f18`).

As dumping the parsing log makes only sense for instrumented parses, we
set Fortran::parser::Options::instrumentedParse to `True` when
`-fdebug-dump-parsing-log` is used. This is consistent with `f18`.

To facilitate tweaking the configuration of the frontend based on the
action being requested, `setUpFrontendBasedOnAction` is introduced in
CompilerInvocation.cpp.
